well, since the earth's seasons are controlled by the 23.44degree axial tilt
and the tilt precesses over a 47,000 year period, you could simply wait
around for 47,000 years to find out...
But I'll also point out that ice ages come on a pretty
reliable 47,000-50,000 year period
Please also note that the warmest days of our year occour 1/6 of a
year AFTER we get maximum sunshine just as the coldest and worst of winter weather "lags" by the same ammount.
Frankly I'd expect if you lived long enough you'd see that since we are just
past the Winter Solstice when perhelion occours that we are past the bottom
point, so global temperatures could reasonably be expected to plunge in the
next few centuries
Consider that the solstice cycle gives us a year of 365 days, but axial
tilt precession gives us another period of rotation of 470 centuries.
and consider the effects you'd see from that...
can you say "Global warming my ass"?
IT's gonna get cold, damned cold. mabey not in our lifetimes,
but the panic mongering Al Gore will also be dead and his
decendants will be spending the near billion dollars he's
accumulated from being the guy
saying that the sky is falling
